"America shouldn’t have a president whose words would make you embarrassed if your children repeated them," Cruz said during a speech in Stafford, Texas. "Our president should make us all proud, should inspire hope in all of us."
A confident Cruz rattled off a list of criticisms against Trump's stances on healthcare, Planned Parenthood and immigration.
Cruz sought to tie Trump to Washington, arguing the GOP front-runner will cut deals with Democrats.
"If you're angry with Washington, I understand," Cruz continued, "But Donald Trump has been part of the Washington corruption for 40 years."
Cruz also pressed Trump to approve the release of audio from an off-the-record meeting with The New York Times editorial board.
Critics have questioned if Trump spoke about his plans on immigration and asked him to reveal the conversation.
"If you’re telling the New York Times editorial board that you’re lying to the voters, the voters have a right to know," Cruz said.
Cruz spoke before supporters after racking up wins in his home state of Texas and neighboring Oklahoma.
Trump won in six other states and looked to extend his massive delegate lead.
Cruz was expected to win the Lone Star State, where some recent polls showed him leading Trump by double digits.
But the senator has pinned his broader hopes on winning a number of Southern states that have larger contingencies of evangelical voters. Many of those states fell in Trump's column.
Cruz pleaded with his Republican rivals to unite behind him to beat Trump.
"Head-to-head, our campaign beats Donald Trump resoundingly, but for that to happen we must come together," the Texas senator said.
Cruz pressed other candidates, including Marco RubioMarco RubioRubio apologized to Trump for 'small hands' crack Sunday shows preview: Bernie soldiers on Fla. Senate candidate bashes Rubio MORE and Ben Carson, to end their campaigns if they aren't able to win key states.
"Republicans, together we have a choice. We are blessed with a deep, talented, honorable field," Cruz said.
"For the candidates who have not yet won a state, who have not racked up significant delegates, I ask you to prayerfully consider our coming together, uniting," he continued. "That is the only way to beat Donald Trump."
Results showed Kasich challenging Trump for Vermont and Rubio ahead in Minnesota. Carson failed to finish in the top three in any Super Tuesday state.
So far, Rubio has not won a Super Tuesday contest. Trump's victory in Virginia delivered a major blow to the Florida senator, who pinned his hopes on winning the state.
Rubio is also trailing Trump in his home state of Florida, recent polls show.
